I think that, to make bold statements about grasping immersive reading you need also to immerse yourself in the science. My view goes against the conventional understanding of reading, but developed and is developing in constant conversation with a wealth of literature from various subdomains and in the context of conflicting perspectives within the literature. My apriori going in were and are shaped by paying close attention to the obsessions and attunements of masters of the craft of type-design and typography, as well as to initiatives like yours and Bloemsma's.
As I said in Thessaloniki years ago, it's an ever-expanding sea to drink and a conflicting maze of wandering paths, but it can be wonderfully productive.
